9.3x62 Loads needed.

[tophet1]

Well I finally have some Boolits from my NOE group buy mold. My FN GC's weigh 286 grains and the HP GC's 280 grains.

I have a custom sizeing die for my Lyman 450. The .375 GC's go on very well with a slightly concave base. Lube is SPG. I have pure wool felt wads.

I am now ready to try some loads. I have done a search and it seems 1,800 fps is the max.. Keeping in mind I only have access to Trail Boss and Aussie powders.

does anyone have a starting load please ?

Well one advantage of having had three weeks leave and exclusive access to a 900 yards rifle range 2.5km from my back door is that I can race out and check loads.

Recommended loads with jacketed projectiles and 2206H/H4895 are:
51 grains (2,130) to 56.5 (2,405)

I took 60% of the max load which came to approx. 35 grains 2206H/H4895. My cast FN projectiles were seated so the GC was level with the base of the case neck and the start of the shoulder. A single circular woolen wad was placed on top of the powder column and seemed to hold it stable. This gives off a distinctive lanolin smell once fired (and burnt). Cases are Norma, Primers Rem 9 1/2. I set up my target at 50 yards for these resuls.

35 grns 1.710" group in a vertical line
36 grns 1.480" in a perfect, neat, triangle
37 grns 2.535" again in a straight line
38 grns 2.305" triangle

My chronograph is currently with a friend so I couldn't measure velocitys. If the 36 grain load holds to 3" at 100 yards I'd be happy. Can it be improved ?

What should I do now ? Keep increaing the charge of powder ? I'm happy to try 2208/Varget. Should I add more tin and make the projectiles harder ?

Well I've had a bit of luck.

All tests were two rounds into a target at 50 yards.

25 grains 2207 with two wool wads 2.315"
54 grains 2209 with no wads 1.090"
51 grains 2206H with one wool wad 0.480"

I think we have a winner with the 2206H (H4895).
I will try it again at 100 yards when I get a chance.
